To all whom it may concern:

Be it known that I, DAVID P. Moons, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Fluid-Hydrocarbon Burners, of which the following is a specification, reference being had therein to the accompanying drawing. I

This invention relatesto improvements in fluid hydro-carbon burners, and has special reference to an improved form of burner, which is adapted to consume light, medium and heavy or crude oils, smokelessly and with intense heat, thereby adapting itself for use in low pressure steam or air blast furnaces, or for use in cupola or glass furnaces.-

To attain this end, my burner consists primarily of a casting which is adapted to be inserted and held within the wall of the furnace, so that air or steam and oil are admitted exteriorly of the wall, and projected into and through the burner into the furnace, the said burner 'being provided with an atomizer and an auxiliary atomizer, the combination of which, I find gives the best possible results in complete combustion and the direction of the blast.

To clearly illustrate my invention, atten-.

tion is invited to the accompanying drawings, in which:

Figurel is a side elevation of my burner in'use in the wall of a furnace. Fig. 2 is a longitudinal section through the burner.

Fig. 3 is a section on line ma:, Fig. 2.

Fig. 4 is a front elevation.- Fig. 5 is a longitudinal section through a modified form of burner. Fig. '6 is a detail viewof the auxiliary atomizer as used in Fig. 5, and Figs. 7 and 8 are detail views of an adjustable oil nozzle.

Referring to the drawings :A designates the wall of -the furnace, in which is set or secured the rectangular end B, of the casting or burner,

Projecting-exteriorly of the wall and ntegral; with B, is the tapered blast pipe attaching end 1. Provided longitudinally of the casting is the tapered channel or core 2, which is'provided with the small entrance end 2, arid the large exit end 2*. In the upper portion of the reduced end of the I provide a threaded opening 3, in which is mounted the pipe and nozzle support 4, the supply pipe 5 and pipe 5, and upon the oil nozzle 6, being carried thereby. The central line of the nozzle is substantially the line 00-02, of Fig. 2 and thus the oil under pressure, which is controlled by the valve 7, is introduced through the nozzle 6, into the channel 2, of the burner.

Formed integral with the casting and de pending by means of the support 9, is the ovoidal spreader or atomizer 8, the lowest point of which is substantially on the line 02-00. The-open ring 10 or what I term the auxiliary atomizer, having its opening 11, toward the nozzle 6, has its axle or support 12, journaled in the reduced end of the casing, substantially on line 00-00, the said axle being rotatable, so that the ring can assume various positions, as shown in full and dotted lines, Fig. 2. When this ring has been turned at its proper or desired adjustment, the lock nut 13 is employed to retain and lock the axle against movement, the adjustment being accomplished entirely from the exterior of the furnace.

In order to prevent the oil from flowing backward into the blast pipe, when the blast is shut-ofi', or when more oil is delivered to the burner than can be at that time consume'tl, the dam 14, which is a small wedgeshaped portion'with a straight edge toward other end, is provided. I have alsofound it unnecessary on account of this dam 14:, to have the burner exactly on a horizontal line.

When it is desired to use light oils, the

diameter of the ring 10 is reduced, that is a the said grid being vertically adjustable through the medium of the threaded supporting and adjusting medium 12. By this means the grid is moved up or down in front of the nozzle 6, and thus acts in a similar manner to the ring 10'. v

The nozzle shown in-Figs. 'Z and 8, has a ball 6, carried upon the lower end of the this ball, is adjustably mounted the globular casing 6", which carries the nozzle or spout 6'. In order to ad just this nozzle or spoutand allow itto asthe blast entrance and inclined toward the sume the position shown in full and dotted lines Fig. 7, I employ the rod 6*, which is journaled in the wall of the burner and has its operating knob 6 accessible from the exterior. To adjust the nozzle and cause it to assume the position shown in full or dotted lines, Fig. 7, the rod 6 is turned or rotated slightly in its journal or the wall of the burner, this turning action causing the ball-and-socket joint of the nozzle to move, so as to project the nozzle in the direction desired, that is either toward the bottom or top of the burner or directly toward the atomizers. By this rod 6 the adj ustment of the'nozzle may be changed at pleasure.

The operation of my improved fluid hydro-carbon burner is about as follows 2- The blast is introduced through the end 2 while the oil under pressure is introduced into the channel through the nozzle 6. The

ovoidal spreader or atomizer and the open ring 10 or grid 10, serve to separate the oil stream and atomize it, the ring andgrid being adjustable so as to regulate the direction of projection of the oil. Previous to the atomizing of the oil, a piece of waste saturated with oil, is thrown into the furnace, then ignited with flame, so that when the oil is properly atomized into the furnace, the same ignites at the mouth of the burner, and the flame is directed through the end 2", of the burner.

What I claim, is

1. In a burner, the combination of 2. casing having a tapered channel, means for delivering fluid hydro-carbon at the center line of said channel, a stationary atomizer mounted in said channel and having its lowest portion on said center line thereof, and an adjustable auxiliary atomizer intermediate of the delivering means and the stationary atomizer.

2. In a burner, the combination of a casing'having a tapered channel, a fluid delivering pipe discharging the fluid at substantially the axial center of the channel, an atomizer having its lowest point in line with said axial center, and an auxiliary atomizer interposed between the dischargeand the first mentioned atomizer.

3. In a burner, the combination of a casing having a tapered channel, a fluid delivering pipe discharging the fluidat substantially the axial center of the channel, an atomizer having its lowest point in line with said axial center, and an adjustable auxiliary atomizer interposed between the fluid discharge and the first mentioned atomizer.

4. In a burner, the combination of a casing having a blast and fluid conducting channel, a fluid discharge nozzle at the center line of said channel, an atomizer mounted in said channel near the discharge end thereof and wholly above said center line of the channel, and an auxiliary atomizer interposed between the fluid discharge and said first named atomizer.

5. In a burner, the combination of a casing having a blast and hydro-carbon fluid conducting channel therethrough, a fluid discharge nozzle in said channel, an atomizer stationarily mounted in the channel near the discharge end thereof, and an open ring journaled in the channel intermediate of the discharge and the atomizer.

6. In a burner, the combination of 2. casing having a tapering blast and hydrocarbon fluid conducting channel, a fluid discharge nozzle at the axial center of the channel, a stationary atomizer having its lowest point in line with said axial center, a pivoted open ring interposed between the fluid discharge and the stationary atomizer, and means exterior of the casing for adjusting said ring.

7. In a burner, the combination of a casing having a tapering blast channel therethrough, a fluid discharge nozzle detachably mounted in the channel near the smaller end, a stationary atomizer depending from the upper portion of and within the chan nel near the larger end, an auxiliary atomizer mounted within'the channel intermediate of the stationary atomizer and the fluid discharge, and means operable from the exterior of the casing for adjusting said auxiliary atomizer. v

8. In a burner, the combination of acasing havinga tapering blast channel there through, the blast being admitted in the smaller end, a pipe, for feeding fluid into said channel, a fluid discharge nozzle adjustably and detachably mounted upon said pipe within the channel near the smaller end thereof, a stationary atomizer depending from the upper portion of and within the channel near the larger end, an auxiliary atomizer mounted with1n the channel intermediate of the stationary atomizer and the nozzle, and means operable from the extericr of the casing for adjusting said auxiliary atomizer.

9. in a burner, the combination of a casing having a blast and hydro-carbon fluid conducting channel therethrough, a fluid discharge nozzle in said channel, an open ring pivotally mounted within the channel and againstwhich the fluid is discharged, and means exterior of the casing for adjusting said. ring.

In testimony whereof I aflix my signature in presence of two WliLIlBSSBS.
